Doesn’t appear to be a good alternative to the Anker 10,000 mAh battery which is slightly cheaper (unless you’ve unlocked free shipping) and has higher output amperage (faster charge). Can be acquired from Woot’s Greek-female-warrior-inspired overlord.
I normally don’t pick on Woot sales, but the Anker has good reviews and a friend of mine has one and likes it.
Actually I made a large pack from 8 C cells and a buck processor each four cells in series for 6 volts; apparently that runs about 15,600 mAh for alkalines, and 9,000 mAh for NiMH batteries. Of course, it weights a ton…
Funny everytime I see something like this pop up on woot I MUST check it simply for my own morbid curiosity.
Anyways, I bought one of those RAV’s and so far its been holding up to what I have personally tested in external mAh battery life to not be a fake and hold its true market advertised capacity.
Oh yea, but I didnt buy it on eBay AND I still paid less than half of this cost for a brand new one.
PS - 10k mAh in your pocket is great when ur out camping and everyone is dyeing for a digital fix or a camera recharge
Recent personal experience has taught me that one needs to be very careful about the output on these - A faster charge to Li batteries is not necessarily a good thing - if it’s jammin’ in there it can become too warm and expand (inside your device.)
Maybe the rock I live under doesn’t get much sun, but this ‘known issue’ was news to me when I had to get a new battery and luckily not a new phone.
Bought 3 of these. So far, these do not charge two items at once like they show on their website. It’s either ipad or iphone but both at once shuts the thing down (assuming it gets too hot, but this is a guess). Otherwise, it does charge.
